g1 engine
An engine of 40 h.p. or higher, such as this 48 h.p.2-cycle engine, is used to power the G-1.
(Visit our Engines Page)

Developed, tested and sold in the 1970's by Compcop, the G-1 was designed to fill the need for an affordable, easy-to-build ultralight helicopter. The entire helicopter can be built at home with ordinary tools at a low cost. No license is required to fly the G-1 because it is in the license-free "Ultralight Aircraft" category (see FAR Part 103).
        The construction manual provides all the details needed to build the G-1, and the included Catalog gives sources of parts and materials.
